As I see it, this topic presumes that "the flood" happened - The question then is how did this flood come to cause/include the ice age. It is not the place for the usual why/how the flood happened/didn't happen debate.
I also presume that Peeta Mellark is going to operate in the young Earth creationist (YEC) time-frame (Peeta needs to make it clear if such is not the case). As such, the question is, how did it happen in such a restricted time frame?
I suspect that Coyote will wish to point out that the most recent ice age lasted longer than that YEC time-frame. If so, I think he needs to make the case of why it couldn't have happened in the YEC time-frame. Something other than citing his favorite old Earth radiometric age dates.

Or something like that.
